You probably have to dig deeper in "config.log", as the above output
are not really errors. The configure script works with different
compilers, some use -V, some -qversion. GCC doesn't use those, it uses
-v. There should be a successful test in config.log which checked for
-v.

Can you paste libgcc's config.log at some pastebin? I guess
it should be
at /home/pi/gcc-4.7.1/objdir/arm-linux-gnueabihf/libgcc/config.log
